Application led January 8, 1925. Serial No. 1,159.'

My invention relates to the book-binding art and particularly tomachines adapted to measure and shape the back and covers to be used informing a volume.

The principal object of myinvention is to provide a machine for thispurpose which will receive a stiff, flat strip of cardboard, or thelike, (preferably furnished in standard size) designed to form the twocovers and back, and to compress it transversely at the proper places tolit the volume under construction, so as to form breaks, or hinges,v inthe cardboard so that the covers will be at substantially right. anglesto the back and one or both Vof the vcovers will have4 a hinge so that.it may be raised from the leaves bound into the book.

My device, as illustrated, also incorpo-l rates means for compressinglthe sheets and covers to be bound as well as means for drilling forbinding, but primarily my invention resides in a machine for receivingthe cover and back forming cardboard and shaping it to the volume underconstruction and providing it with hinges whereby the cover or coversmay be raised from the leaves and I do not desire tobe limited in thescope'ofmy protection except as specified in the accompanying claims. i

My invention consists of the details of construct-ion as set forthherein and pointed out in my claims, the illustration disclosing apreferred form of construction.

Clin the accompanying drawings- Fig. 1 shows a perspective view of thatportion of a binding machine necessary, or desirable, for illustratingmy invention, which is shown attached thereto, a part-,of the crimpingbar being broken away;

Fig. 2 shows a sectional view of the con.

nection between the carriage for the crimping bar I employ and the pushrod which controls its positionin^ andthe slidable connection of thispush rod with the binding machine;

Fig. 3 shows the cardboard before treatment in the machine;

Fig. 4 shows the cardboard after its first treatment in the machine; and

Fig. 5 shows it after its second treatment therein and compressed andready to fit to the volume under construction.

Referring to the accompanying drawings, the reference numerals and 11indicate the base supports of the machine with vertical standards 13 and14 rising therefrom.

'.l'he cross' bars 15 and 16 join the base supports, as shown, `andadrill carriage 17' is slidably mounted thereon, an alinement cross bar18 also being employed, for obvious purposes. l Y v f ylire assemblybase 19 is mounted on-t'he vertical standards v13 and 14 anda pressurebar 20 is mounted for vertical movement. on screw threaded verticalshafts, 21 and 22, projecting upwardly from the assembly base.

lof the machine, one onv either side thereof. rl`hepressure bar is,preferably,recessed asv shown at l23 to permit the drills to passtherethrough and also to permit `of binding the volume before removalfrom the machine. 1

A, rod, or lug,v 24 projects outwardly from one end of the pressure barits under surface engaging one arm 25 of a bell crank lever, the otherarm 26 being pivotally connected to the push rod `27, anchored forslidable `movement to. theassembly base 19, said push rod being heldunder tension,lpreferably, by a coil spring28. The bell crank leverispivotally mounted to a bracket 29 secured to the assembly base 19. 'v

The forward end of the push rod 27 is loosely connected to the carriage30 to which Y 4 the crimping, or compressing leverf31r is secured. Thecarriage 30 is pivotally mounted to the base supports Iat 32 and 33and'- moves radially from these mountings as it is controlled by thepushing, orvpulling, movement of the push rod 27. 'The crimping lever 31has on its under surface the male members' 34 and 35 `of the crimpingmeans, the female membersbeing in the base bar 36 which receives thecrimping lever;

' The mounting for the crimping leveris at one end of the carriage 30and is 'preferably/iv of the bell crank typeas shown at37, the oppositeend of the crimping lever projecting beyond the side of the machine andter-- minating in a handle 38. f

By construction the machine is so formed that the settingy of thepressure bar 2O to compress the cover and leaves moves the push rod 27(through the operation of the bell crank'lever with the arms 25 and26)to the proper place for positioning the carriage 30 so that theoperation of the crimping lever 31 will crease the cardboard, designedto form the cover and backs, in the proper place so that the back willfit the volume under construction.

A retaining bar 39 (L shaped Ain cross seclOO tion) is designed to fitabove the forward v end of thev pressure bar and to be secured theretofor purposes hereinafter set forth.

For purposes of illustrating the operation of my device the numeral 40indicates the cardboard before treatment in the machine, the numerals 41and 42 the creases which form the hinges for the covers and 43 and 44the creases providing the meansyfor bending the back to a substantiallyright angular position with the covers before fitting and securing it tothe volume being built.

In practical operation the cardboard designed to form the back andcovers for a volume is of a standard size `as shown at 40. The properlength for the cover is determined by the operator and the cardboardinserted in the crimping' device and the creases 41 and 43 formed by oneoperation of the lever 31. The cover is then placed, at proper position,on the assembly base and the sheets to be bound placed thereon. Thepressure bar is then lowered to engage and compress the sheets on thetop of this cover. (The means, other than screw threaded shafts on whichthe pressure barI travels, is not shown as it is not vessential to myinvention and is also comprised o`f any ordinary or desiredconstruction.) As the pressure bar moves downwardly it moves the pushrod 27 rearwardly thus bringing the carriage 30 closer to the assemblybase. When the pressure bar is tightly compressed against the leavesforming the volume it is obvious this will. determine the thickness ofthe volume beingr formed, and this positioning of the pressure bar hasmoved the carriage 30 into proper 'relative position that the cardboardextending over the bar 36 (the crimping lever 31 has been placed inelevated position) is properly positioned to receive the creases 42 and44, formed by the lowering and pressing of the crimping lever, so thatthe distance` between the creases 43and 44 is the same as the thicknessof the volume being constructed. The cardboard after the second crimpingis bent up over the forward end of the volume, the back portion abuttingthe ends of the sheets to be bound, and the upper part of the cardboardis then bent rearwardly the portion between the creases 42 and 44 beingpressed against the upper surface of the pressure bar, and the partextending from the crease 42 projecting upwardly from the right angularformation at the front of the pressure bar. The retaining bar 39 is thenplaced on top of the cardboard and secured to the pressure bar, thisoperation firmly securing the upper portion of the cardboard to thepressure bar-that part between the creases 42 and 44 being in ahorizontal position and that part beyond the crease 42 projectingupwardly. The retaining bar 39 is preferably recessed at 45 to registerwith the recesses 23 in the pressure bar. While the cover and leaves areheld in this position they are bound into the volume and then removedfrom the machine.

Having thus described my inventionwhat flat strip of cardboard; meanspositioned by the setting of the compression means to measure thecardboard to fit the volume under construction; means to shape thecardboard to form a back and hinged covers to lit said volume.

3. In combination with a book-binding machine having a pressure bar; acarriage pivotally secured to the machine; means associated-with thepressure bar for positioning 'the carriage; a crimping bar on saidcarriage.

4. In combination with a book-bindingv machine having a pressure bar; acarriage pivotally mounted to the machine; a crimping bar carried bysaid carriage; means whereby the positioning of the ressure bar movesthe carriage to position or properly crimping a flat strip of cardboardto fit the volume under construction.

5. In combination with a book-binding machine, having means to compressa volume under construction, means to receive a flat strip of cardboard;means positioned by the setting of the compression means to measure thecardboard to fit the volume under construction; means' to shape thecardboard to form a back and hinged covers to fit said volume; and meansto hold the shaped cardboard in position in the machine during thebinding operation.
